Probing the low-mass end of the companion mass function for O-type stars
M. Reggiani, A. Rainot, H. Sana +6
Almost all massive stars are part of a binary system. Given the wide range of separations at which these companions are found, several observational techniques have been adopted to…
Detailed models of interacting short-period massive binary stars
K. Sen, N. Langer, P. Marchant +10
About a quarter of massive binary stars undergo mass transfer while both stars burn hydrogen at their cores, first on the thermal and then on the nuclear timescale. The nuclear tim…
Binary-object spectral-synthesis in 3D (BOSS-3D) -- Modelling H-alpha emission in the enigmatic multiple system LB-1
L. Hennicker, N. D. Kee, T. Shenar +5
Context: To quantitatively decode the information stored within an observed spectrum, detailed modelling of the physical state and accurate radiative transfer solution schemes are…
The Carina High-contrast Imaging Project for massive Stars (CHIPS): II. O stars in Trumpler~14
Alan Rainot, Maddalena Reggiani, Hugues Sana +2
Most massive stars belong to multiple systems, yet the formation process leading to such high multiplicity remains insufficiently understood. To help constrain the different format…
The CubeSpec space mission. I. Asteroseismology of massive stars from time series optical spectroscopy: science requirements and target list prioritisation
D. M. Bowman, B. Vandenbussche, H. Sana +7
Context. There is currently a niche for providing high-cadence, high resolution, time-series optical spectroscopy from space, which can be filled by using a low-cost cubesat missio…
Uncovering astrometric black hole binaries with massive main-sequence companions with Gaia
S. Janssens, T. Shenar, H. Sana +6
The hunt for compact objects is on. Rarely seen massive binaries with a compact object are a crucial phase in the evolution towards compact object mergers. In Gaia data release 3 (…
